Specifications of the Lantic Radeon HD 5670 GPU


Lantic Radeon HD 5670 (part number A5670D3-1GDVH) is a desktop Graphics Processing Unit, based on ATI Radeon HD 5670, and built on 40 nm technology. The card has graphics clocked at 725 MHz. Furthermore, it has 400 stream processors, 8 color ROPs, as well as 20 texture units. The Radeon HD 5670 embeds 1 GB of GDDR3 memory. Since the memory operates at 650 MHz, and uses 128 bit bus, the effective memory bandwidth is 20.8 GB/s. The GPU supports PCI Express 2.1 interface, and needs 2 slots on the motherboard. This model requires up to 64 Watt of power, identical to the reference design. 3D graphics and game performance of the Lantic Radeon HD 5670 can be improved if it is paired with another graphics card.
